Which AWS service provides a simple and scalable shared file storage solution for use with Linux-based AWS and on-premises servers? A. Amazon S3 B. Amazon Glacier C. Amazon EBS D. Amazon EFS
Answer: D
Explanation:
Explanation:
Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file
system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to
petabytes without disrupting applications, growing and shrinking automatically as you add and remove files,
eliminating the need to provision and manage capacity to accommodate growth.
Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for Linux workloads.
Throughput and IOPS scale as a file system grows and can burst to higher throughput levels for short
periods of time to support the unpredictable performance needs of file workloads. For the most demanding
workloads, Amazon EFS can support performance over 10GB/sec and up to 500,000 IOPS.

Instead of defining permissions for individual IAM users, it’s usually more convenient to create groups that
relate to job functions (administrators, developers, accounting, etc.). Next, define the relevant permissions
for each group. Finally, assign IAM users to those groups. All the users in an IAM group inherit the
permissions assigned to thegroup. That way, you can make changes for everyone in a group in just one
place. As people move around in your company, you can simply change what IAM group their IAM user belongs to.
